Used Electronics Showcase Website Design

I need a sleek, modern-looking website that simply showcases the pre-owned phones, laptops, and gadgets I carry in my physical store. For now the site only needs one well-structured Home page, but that page should do a lot of heavy lifting: highlight featured items with crisp photos, introduce my brand story, and make it easy for visitors to see what’s currently in stock and how to reach me offline.

There's a website in PDF format that I want to find one like. The PDF is below the project.

Nothing will be sold through the site yet—the goal is pure product display—so an intuitive gallery or grid layout, clear category filters, and quick-loading media are essential. The overall style must stay clean and contemporary, avoiding clutter while still giving each device the space to shine.
